[QUOTE="Andy Ful, post: 835777, member: 32260"] OSArmor is not intended to block signed EXE files. It can block them when they are run from suspicious locations. It can also block some LOLBins, etc. [LIST=1] [*]The first sample was JS script and wscript.exe (scripting interpreter) was blocked. [*]The second was HTA scriptlet and mshta.exe sponsor was blocked. [*]The third was CMD script and cmd.exe sponsor was blocked. [*]The fourth was weaponized document with a macro that tried to run VBE script - this one was blocked by anti-exploit feature for MS Word. [*]The fifth was unsigned EXE and this one was blocked directly by Desktop protection from unsigned executables. [*]The last was signed EXE - allowed by design to run from the Desktop. [/LIST] Technically, the last sample did not bypass OSArmor, because signed EXE files are allowed by design to run from Desktop. [/QUOTE]
